Iron has the configuration
Explanation:
Electron configurations of elements can be a bit confusing, and the transition metals are a case in point.
#1s^2 2s^2 2p^6 3s^2 3p^6 3d^6 4s^2# .
A point to be noted :
Note that the 4s orbitals are filled AFTER you add six electrons to the 3d orbitals. The 3d orbitals belong with the n=3 orbitals.
So, you will have
2 electrons in the n=1 (1s) shell,
8 in the n=2 (2s and 2p) shell,
8+6 = 14 in the n=3 (3s, 3p, and 3d) shell,
2 in the n=4 (4s) shell.
